+Fixed Voltage regulators
+
+Required properties:
+- compatible: Must be "regulator-fixed";
+
+Optional properties:
+- gpio: gpio to use for enable control
+- startup-delay-us: startup time in microseconds
+- enable-active-high: Polarity of GPIO is Active high
+If this property is missing, the default assumed is Active low.
+- gpio-open-drain: GPIO is open drain type.
+ If this property is missing then default assumption is false.
+-vin-supply: Input supply name.
+
+Any property defined as part of the core regulator
+binding, defined in regulator.txt, can also be used.
+However a fixed voltage regulator is expected to have the
+regulator-min-microvolt and regulator-max-microvolt
+to be the same.
+
+Example:
+
+ abc: fixedregulator@0 {
+ compatible = "regulator-fixed";
+ regulator-name = "fixed-supply";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <1800000>;
+ gpio = <&gpio1 16 0>;
+ startup-delay-us = <70000>;
+ enable-active-high;
+ regulator-boot-on;
+ gpio-open-drain;
+ vin-supply = <&parent_reg>;
+ };
